Portfolio structure

Your targets and current weights, together

The rulebook gives each position a role and each sleeve a target. CornerScope shows how the current weight differs from that target.

Your rules

Choose a method and make it yours

You can start with an existing rulebook or build your own. You can inspect its rules before assigning it to a portfolio.

Make your method the rulebook

Describe how you invest in your own words. CornerScope gives you a prompt to use with ChatGPT, Claude, Gemini or another assistant, then checks the rulebook you paste back before you can import it. CornerScope never sends your description to an assistant itself; after you import and activate the rulebook, it applies those rules when it evaluates your portfolio.
